Abstract

The invention refers to a method in a user equipment, UE (200), for handling radio link failures, wherein the UE is connected to a radio communication network by means of a plurality of uplink, UL, carriers (220, 230), comprising: monitoring (S41) retransmissions of radio link control, RLC, data packets for at least two of the plurality of UL carriers, determining (S42) a failure of RLC data packet transmissions with respect to one of the UL carriers, and providing (S43) an information indicative of the failure and said UL carrier; the invention further refers to a method in the UE (200), for handling radio link failures, wherein the UE is connected to a radio communication network by means of a plurality of UL carriers (210, 220, 230), comprising performing (S61) retransmissions of a certain RLC data packet on at least two of the plurality of UL carriers, monitoring (S62) retransmissions of a radio link control, RLC, data packet commonly for bthe at least two UL carriers, and providing (S63) an information indicative of a common RLF; the invention further refers to corresponding methods in a base station (100), corresponding UEs (200) and base stations (100), a corresponding communication system and a corresponding method in the communication system.
